Merge branch 'rcu-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU fixes from Ingo Molnar:
"This fixes sporadic ACPI related hangs in synchronize_rcu() that were
caused by the ACPI code mistakenly relying on an aspect of RCU that
was neither promised to work nor reliable but which happened to work -
until in v4.9 we changed the RCU implementation, which made the hangs
more prominent.
Since the mis-use of the RCU facility wasn't properly detected and
prevented either, these fixes make the RCU side work reliably instead
of working around the problem in the ACPI code.
Hence the slightly larger diffstat that goes beyond the normal scope
of RCU fixes in -rc kernels"
